Apple today released the second beta of iOS 8 to developers, just over two weeks after unveiling the new operating system at its Worldwide Developers Conference. The update, build number 12A4297e, is available through Apple's over-the-air updating system on iOS devices and will also be available via the iOS Dev Center.

MacRumors forum users are tracking new changes and features found in Beta 2 in this thread.

iOS 8 introduces a range of new features, including improved integration with OS X through Continuity, a Health app, Family Sharing features, interactive notifications, a new QuickType Keyboard and improvements to several apps like Safari, Mail, and Messages.

iOS 8 is only available to developers at the current point in time, but it is expected to be released to the public this fall after several additional beta iterations. Based on past history, iOS 8 will likely be released alongside new iPhones, and possibly the much-rumored iWatch.

The second iOS 8 beta includes several tweaks to the operating system, such as a permanent Podcasts app that now comes pre-installed and QuickType for the iPad. Safari is also able to block ads that redirect to the App Store, and there's a new iCloud Photos popup that replaces Photo Stream when the Photos app is opened for the first time. For a full list of changes to iOS 8 in beta 2, make sure to check out our beta 2 tidbits post.

So how's it going? I held off on installing the first beta because there were no compelling features I wanted to immediately start playing with, and I figured I'd try it out a little later. Is iOS 8 decently stable? What are your favorite new features?

It's been out for 5 minutes, most people won't have aven been able to download it yet.

As long as iCloud documents are not compatible with Mavericks, I cannot update my devices. This is from the release notes:
Notes
Upon upgrading to iOS 8 Beta, existing iCloud Documents & Data present (not evicted) on your device are copied into special server-side containers for use during the beta period.
iCloud Documents & Data created with iOS 8 Beta will not sync with with Documents and Data managed with iOS 7, OS X Mavericks, or earlier operating systems.
iCloud Documents & Data in iOS 8 Beta will only sync with devices running iOS 8 and OS X Yosemite Developer Preview.
iCloud Documents & Data managed with iOS 7 or OS X Mavericks will remain unaffected.
iCloud Documents & Data created with iOS 8 Beta will be deleted from the servers at some point during the beta period. Information downloaded and not evicted from the device will remain on device and will re-sync after the data wipe occurs.
The UI for managing iCloud Documents & Data does not show the documents and data for iOS 8 Beta and OS X Yosemite Developer Preview. It only shows the documents and data synced with previous operating systems.
